Subject[PATCH 026/105] xen-netback: remove redundent parameter in netbk_count_requests
Date
3.8.13.4 -stable review patch.  If anyone has any objections, please let me know.

------------------

From: Wei Liu <wei.liu2@citrix.com>

commit ac69c26e7accb04ae2cb9ab0872068983a42b3c8 upstream.

Tracking down from the caller, first_idx is always equal to vif->tx.req_cons.
Remove it to avoid confusion.
